Abstract

PURPOSE:To make resolution process continuous smoothly by feeding seed crystals to a resolution tank contg. racemic modification in early stage in order to break a portion of grown active substance so as to eliminate complexity of making a large number of seed crystals through self-replenishment of seed crystals.
